IMPROVEMENT IN COAL-SIITER.

The Schedule referred to in these Letters Patent and making part of the same.

sifted, and the coal put back on to the fire again, if de sired, without creating adust in the room; also saving labor of carrying said coal from room to room, or handling it a second, and sometimes a third time.

A is the cover, made with hinge to turn back and rest on handle 1, which is kept in right position by the ends of the bail being turned back at the ears.

B isthe grate or sieve, made of cast-iron, wire,or other metal, with handle attached, which projects through a slot out in the back of the hod, where it moves'i'rom side to side.

The grate rests on its outer edge, unless it is very heavily loaded, whenit may also rest on the'base of pin, around which it moves. It has a hole through its centre to fit said'pin.

It is kept in its place, when the coal is emptied,by the handle and shape of the hod, which is smaller above than below it.

It may also be kept in its-place by a little pin, put through the centre-pin, above the grate.

O is the grate-holder. It is made of iron; has three (3) or four (4) arms, the outer ends of which are a little thicker than the rest, so that the grate may rest on as little surface as possible, thereby saving friction.

There is a pin in its centre, which fits a hole in the grate. It rests on small sheet-iron brackets, riveted on to the inside of the hod. They are made 'to fit tight on the sides of the arms, to prevent its working loose. They may also be bent over the tops of the arms.

D is a piece of sheet-iron or tin, made in the shape of a tunnel or inclined collar.

It is riveted on to the inside of the hod, the bottom coming close to the opening in the bottom of the hod. Its use is to prevent ashes remaining, when the slide E is pulled out to empty them.

E is a slide on the under side of the bottom of the hod, stopping opening there entirely when coal or ashes are being sifted in the house.

It is drawn out and shoved in by handle F. Q is a tin spring, or its equivalent, made twice as long and twice as wide, at least, as the slot.

It is fitted on to the inside of the handle of the grate,

and moves with it, thereby closing the slot all the time. I claim as my improvement The arrangement and combinationof the grate B, handle H, spring-cover-No. 2, inclinecollars D D, bottom slide E, in combination with the hod, as shown and described. r I
